Historic rewards and total received rewards are covered by the current work scope of Patrick N. Further work is needed to have an API for historic scheduled rewards.

Total received rewards per module

We are tracking total rewards per participant, but we don't have per-module (or per-smart-contract) granularity. This should be fine for now, as long as there is only one module and one smart contract.

Total number of jobs completed per module

We don't have this information in spark-stats API & our DB.

This is what we have now:
